Privacy Policy for “Plan dnia”
Last updated: 20 July 2026
This document explains what data the “Plan dnia” application processes — in particular data obtained from a Google account — for what purpose, and under what conditions.
In short: the application reads the Google Calendar solely to determine which hours are already occupied by meetings. It never writes to or modifies the calendar. No data is shared with or sold to anyone. There are no cookies, no analytics and no advertising.
1. Data controller
The controller of data processed by “Plan dnia” is:
All privacy-related enquiries and data deletion requests should be sent to the e-mail address above.
2. About the application
“Plan dnia” (Polish for “daily plan”) is a personal daily planner. In the morning it presents the tasks planned for the current day; in the evening it prepares a proposed plan for the next day. It draws data from the Plane project management system, from Google Calendar and from entries created by the user. Notifications are delivered through the Matrix messenger.
The application runs inside the controller’s private network and is not publicly available. This page is informational only.
3. What Google account data is accessed
The application requests a single Google data scope, in its read-only variant:
https://www.googleapis.com/auth/calendar.readonly
This scope allows reading events from the user’s calendars. It does not allow creating, modifying or deleting events. From each event the application uses:
- event title — so the user can recognise what occupies a given time block;
- start and end time — to determine busy time ranges;
- attendance status (accepted, tentative, declined) — to skip meetings the user does not attend.
The application does not access event descriptions, attachments, other attendees’ details, or any other Google account data. It does not access Gmail, Drive, Contacts or Photos.
4. Purpose of processing
The sole purpose of reading the calendar is to identify hours already occupied by meetings, so that planned tasks do not collide with those meetings. Calendar events are displayed to the user alongside the task list in the user’s own daily plan view.
Calendar data is not used for any other purpose — in particular it is not used for profiling, model training, ad targeting or behavioural analysis.
5. Data retention
- Calendar events are retrieved in order to generate the plan for a specific day and are not retained for longer than is necessary to generate and display that plan.
- Event data is not archived and no history is kept beyond the current planning cycle.
- Access credentials (the OAuth token) are stored until the user revokes consent or deletes their account in the application. Once consent is revoked, the credentials are deleted.
- Tasks created by the user are stored until the user deletes them or deletes their account.
6. Data sharing
None. Data obtained from the Google account is not transferred to third parties, sold, traded or shared for marketing purposes. It is not passed to advertising systems, data brokers, or to any models trained on user data.
Access is limited to the controller, and only to the extent necessary to operate and maintain the application. Data is not shared with other users of the application.
7. No cookies, no tracking, no analytics
Neither this website nor the application uses marketing cookies or any tracking tools. There is no web analytics, no tracking pixels, no social plugins and no advertising. The public pages load no resources from external servers.
8. Security measures
- All communication takes place over an encrypted HTTPS connection.
- Google access credentials (OAuth tokens) are stored encrypted.
- The application itself is not exposed to the public internet — access is restricted to the controller’s private network. Only this informational website together with the privacy policy is publicly reachable.
- Server access is protected by cryptographic keys, with password login disabled.
9. Revoking consent and deleting data
Consent for access to Google Calendar can be revoked at any time:
- in Google account settings at https://myaccount.google.com/permissions, by selecting the “Plan dnia” application and removing its access;
- by disconnecting the Google account in the application’s own settings.
After consent is revoked the application loses the ability to read the calendar and the stored credentials are deleted.
A request to delete all data associated with an account — including the user’s own tasks and credentials — can be sent to kontakt@sparktech.com.pl. Requests are handled without undue delay, and no later than within 30 days.
10. Compliance with Google policies
Plan dnia’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
11. Changes to this policy
Should the way data is processed change, this document will be updated and the “Last updated” date at the top of the page will be revised.
